The 11th Division was an Australian Army unit formed during World War II by the renaming of Milne Force in December 1942.

Predominately a Militia formation, the division's main role during the war was as a base command headquarters, although elements saw action in New Guinea against Japanese forces during the Finisterre Range campaign and in New Britain.

In July 1942, a headquarters was raised to command the units that had been sent to Milne Bay, to establish a series of airfields there after the Battle of the Coral Sea.

[1] A further move occurred in July 1943, when the divisional headquarters was flown to Dobodura, assuming responsibility for the area between Oro Bay and Buna from the US 41st Infantry Division.

[2] In April 1944, the corps' headquarters moved to Dumpu and it later relieved the 7th Division, which had been fighting a campaign through the Markham and Ramu Valleys and into the Finisterre Ranges.

[2] Division headquarters remained in Rabaul until late April 1946 during which its constituent units and elements of its staff were repatriated to Australia in individual drafts.
